Hello, I am on the implanon birth control. And I have been experiencing some pregnancy symptoms such as; fluttering in uterus, back pain, acid reflex, I just had some bleeding for two days not much blood but enough to notice. And I have not had a period since feb 2014 when I received my implant. I get cramps on the sides of my uterus. Very fatigue and bloating, I often get sick when smelling things, vomitting. I took a dollar pregnancy test and it was negative. These things have been happening for the past four months.. HELP!!

This is where you go back to your doctor with the symptoms. If I were to hazard a guess I would think that these are just side effects of the birthcontrol. Even more of a reason to see a doctor.
